body so placed that if disturbed it returns to its former
position, as in the case when the center of gravity is
below the point or axis of support; -- opposed to
unstable equilibrium, in which the body if disturbed
does not tend to return to its former position, but to
move farther away from it, as in the case of a body
supported at a point below the center of gravity. Cf.
